Embodiment 1

[0034] Embodiment 1: an inner winding process of a motor, carried out according to the following steps:

[0035] (1) Stator production:

[0036] The inner-wound silicon steel sheets are stacked to form an inner-wound stator; the steel plate is put into the progressive die high-speed punching machine, and the stator riveting is directly completed after the product comes out; the out-of-the-box product passes through the tooling, checks the quality of the stator, and measures its concentricity And verticality, the concentricity between the outer diameter and the inner diameter of the stator is required to be a tolerance level of 7, that is, the tolerance is 0.025mm. When the stack thickness is 12mm, the verticality is required to be a tolerance level of 7, that is, the tolerance is 0.015mm. When the stack thickness is 16mm, the verticality is required. The requirement is a tolerance level of 7, that is, the tolerance is 0.020mm; the size of the notch is 2mm, and the symmetry tol...

Abstract

The invention relates to an internal winding process and in particular to an internal winding process of a motor. The process comprises the steps of stator production; skeleton design and production;skeleton weighing; and putting equipment for winding. The internal winding process of the motor further improves use performance.

Description

technical field [0001] The invention relates to an inner winding process, in particular to an inner winding process of a motor. Background technique [0002] The motor stator is easily damaged when the motor is running for a long time, so it needs to be protected by related parts. However, the service life of the protective plate of general materials is very short, the heat dissipation effect is poor, it is easy to be damaged by heat, and the insulation effect is not good, which is easy to cause high voltage breakdown. [0003] At present, the automatic motor winding machines on the market are all vertical outer winding machines. However, the high-slot full-rate inner-winding brushless motor has a slot in the inner ring of the motor, and some motors have inclined slots. Therefore, The current high-slot full-rate inner-wound brushless motors are all wound manually. There are many disadvantages in manual winding, such as time-consuming, laborious, uneven winding, and easy scr...
